20080266754 | ELECTRODE FOR USE WITH DOUBLE ELECTRIC LAYER ELECTROCHEMICAL CAPACITORS HAVING HIGH SPECIFIC PARAMETERS - The present invention relates to the production of electrochemical capacitors with a DEL. The proposed electrodes with DEL are based on non-metal conducting materials, including porous carbon materials, and are capable of providing for high specific energy, capacity and power parameters of electrochemical capacitors. P-type conductivity and high concentration of holes in electrode materials may be provided by thermal, ionic or electrochemical doping by acceptor impurities; irradiating by high-energy fast particles or quantums; or chemical, electrochemical and/or thermal treatment. The present invention allows for an increase in specific energy, capacity and power parameters, as well as a reduction in the cost of various electrochemical capacitors with DEL. The proposed electrodes with DEL can be used as positive and/or negative electrodes of symmetric and asymmetric electrochemical capacitors with aqueous and non-aqueous electrolytes. | 10-30-2008 |

20080257030 | Petrophysical Fluid Flow Property Determination - A method and apparatus for determining petrophysical parameters within a geologic formation pressurizes a geologic sample through a set of predetermined effective pressures, energizes the sample at each predetermined effective pressure with an electric current and/or sonic energy, and measures a conductivity value (electrical conductivity and/or sonic velocity). Permeability and/or porosity are also measured at each pressure through a traditional method and the functions are compared so that permeability and/or porosity can be subsequently derived from a sonic or electrical measurement of a comparable sample under a effective pressure. An apparatus is also described for acquiring the measurements under tri-axial compression, with a computerized interface in one embodiment. | 10-23-2008 |

20150237210 | CALL TRANSFER USING SESSION INITIATION PROTOCOL (SIP) - A system is provided for providing communication event routing and transfer capability in a multi-site communication-center environment. The system utilizes a presence protocol application and a routing application for determining availability of an agent or system and for setting up the transfer from a point of transfer on a network to a destination of transfer on the same or connected network. In a preferred use the presence protocol application is shared by communication-center sites cooperating in the transfer and routing of events and the presence protocol enables at least one event-handling process normally performed by the routing application. | 08-20-2015 |
